GE Smart Grid Software Will Help PPL Electric Utilities Boost Reliability, Add Clean, Domestic Energy and
Give Pennsylvanians More Power Over Their Power

ATLANTA, GA.—July 21, 2010—60,000 consumers in south-central Pennsylvania won’t notice any
immediate changes—because nobody notices when the lights stay on—but their electric service is
about to become more efficient, reliable and consumer-friendly as PPL Electric Utilities launches a
smart grid project that includes GE’s (NYSE: GE) world-class distribution management system. GE’s
network management software gives PPL Electric Utilities new ways to “see” and control the status,
performance and interaction of equipment throughout its grid. With the ability to see and fix potential
problems before they occur, PPL Electric Utilities can minimize the frequency and duration of power
outages.

“From smart grid technology innovations to rebates, incentives and education, we are always driving
new ways to improve performance for our customers,” said Martha Dodge, senior director of smart
grid projects for PPL Electric Utilities. “The smart grid improvements we’re making will deliver real
benefits for the customers who count on us each day.”

GE’s distribution management system, recognized throughout the world for its ability to improve
electric service, was initially developed for the United Kingdom, where it controls more than 80% of the
distribution grid. This software system is a key element of GE’s companywide commitment, called Grid
IQ, to modernize the world’s infrastructure and make the smart grid smarter. The economic and
lifestyle benefits can be profound, as power interruptions and disturbances cost the U.S. economy
approximately $80 billion each year. *

GE’s network management software collects and analyzes information from across the power grid to control the flow of electricity in response to ever-changing demand. Some of its major accomplishments include:

Outage management technology that can determine the source of a power outage and
automatically route electricity
around it—minimizing the number of customers affected.Grid efficiency technology that balances the loading of power lines in response to real-time power needs—reducing wasted energy, while also minimizing the stress on costly capital assets.Renewable energy integration solutions that make it easy to tap into the clean power generated by
rooftop solar panels and local wind turbines—reducing Pennsylvania’s CO2 emissions that come from
electricity generation.
